The Case for 3D Computer Vision
The importance of 3D computer vision is emphasized, as the world is fundamentally three-dimensional. Understanding our surroundings requires inferring a 3D representation from 2D observations, as all deductions we make pertain to an underlying 3D scene. The speaker argues that any reasoning in computer vision should start with this 3D inference to capture the properties accurately. This approach is essential for tasks that aim for a more general artificial intelligence, asserting that vision is one of the first problems to solve.
